Nvidia Rally Shows Signs of Overheating as Gains Blow Past 80%

Nvidia's stock has surged over 80% in less than four months, adding $1.9 trillion to its market value and making it the world's most valuable company at over $4.2 trillion. This rally is underpinned by continued robust AI spending from major customers and the significant news of the Trump administration's approval for Nvidia to resume some AI chip sales to China, potentially recovering $15 billion in future data center revenue. While technical indicators show the stock is overbought and some investors caution about AI business cyclicality, broader Wall Street sentiment remains bullish, with upcoming Big Tech earnings crucial for insights into sustained AI capital expenditure.

Analysis

Nvidia's stock has demonstrated an extraordinary rally, surging over 80% in under four months to add approximately $1.9 trillion in market value, positioning it as the world's most valuable company at over $4.2 trillion. This momentum is fundamentally driven by two key factors: the resumption of some AI chip sales to China following a US policy reversal, which could recover a significant portion of the $15 billion in fiscal 2026 data center revenue previously at risk, and sustained, large-scale AI spending commitments from key customers like Meta Platforms. Despite this strong fundamental backdrop, technical indicators suggest caution. The 14-day relative strength index (RSI) recently surpassed 80, a level historically associated with overbought conditions and preceding a 20% pullback in June 2024. While the stock's forward P/E ratio of 34 is below its five-year average of 40, some investors are taking profits, citing concerns over rising valuation and the potential for future cyclicality in the AI sector. The market's focus now shifts to the upcoming earnings reports from Alphabet, Microsoft, and Meta, as these firms, along with Amazon, constitute over 40% of Nvidia's revenue and their capital expenditure guidance will be a critical indicator of continued demand.

Key Decisions for Investors

• Investors should closely monitor the upcoming Q2 earnings reports from Microsoft, Meta, and Alphabet for guidance on their capital spending plans, as these key customers represent over 40% of Nvidia's revenue and are a primary driver of its growth outlook.
• Given the 14-day RSI has exceeded 80, indicating a technically overbought condition that previously preceded a significant stock drop, short-term oriented investors may consider trimming positions or implementing risk management strategies to protect recent gains.
• Long-term investors should weigh the strong fundamental tailwinds, including the reopening of the China market and robust AI demand, against the elevated valuation and potential for increased cyclicality in the AI hardware business.
